T an whoi fit ma concern:

Be i known that I, Gnome Ci D RBY, "a

itizen of the United States, residing at San Francisco in the count of San Francisco State of California, have invented cernew and usefulilmprovementsin Air Purifying and Humidifying Apparatus;

I do declare the following to be a full, clear, and exact description of the invention, "such as-will enable others skilled in the art te'which it appertain's to make and use the is-ems;

Ithsis invention relates to ventilation, and mere especially to air moistening, cooling, and cleansing apparatus; and the object of v the same! is to produce a device of this charact-er for purifying. and humidifying air which at no point will cause the water to 'fiow' over the, plates or baifies backward aleng' the draftef air: or to drip across it.

. find that whenthe water has either of "thesemovements'relative to the direction of the blast of air, the latter becomesexcessiv'ely saturated because the'water is broken ftip-ifitD fine particles or spray and is carried -ferward with the airto a greater extent than is desirable. Accordingly I have de -vised an apparatus whose ultimateobject is ts avoid this" excessive humidity, to which end the invention consists in the? details of cens'truction hereinafter more fully cleseribed and claimed and shown in the drawings wherein F1 'linel l of Fig. 2 Fig. Q-i's a horizontal sectiontaken on the line 2-2 of. Fig. 1. Fig. 3

is avertical transverse section taken on the line ti -f. Fig. 1; Fig. 4 is anenlarged cross sectionthrough one of the eliminator plates near the outlet pipe, taken aboutpn v the line 1-l of Fig. 2 and Fig. 5 isahorizontal section on the line 5 5 of F ig. 4;. Fig. 6 is a sectional detail of a slightly mod fied form of one of the eliminator plates.

- By preference. this-entire device is 'con structed of metal, sheet metalbeing used for the plates and gutters and possibly also, for, the skeleton framework, and the metal should betreated to. prevent rust, whilewthe Yexactsizes and proportions of parts areim- "material.

The framework 1 maybe of. any suitable 7 re l. is a vertical longitudinal sectiona view through this device, taken on the to theadmission of fresh air which may be directed thereinto, if desired, by means of a fan, not shown andforming no part of'the present invention. Adjacent this end is arranged a Water-supply system 3, whose pipes have jet nozzles 4L delivering water in ets or sprays toward the rear as shown, and

these nozzles are arranged in staggered rela' tion to each other so that their spray will substantially cover the interior of the apparatus as well known in devices of this character. Next inrear of the wate'r supply sys tem I preferably dispose a series of down- Wardly inclined bafie plates 5 whose front and rear edges may. be reversely bent or flanged as at 6 and 7 desired, although this detail, of construction is not necessary. The

exact angle to -a horizontal at which these.

plates are disposed is immaterial, and their obvious purpose is t-obreak up the current .of air intohorizcntal 'stratarather than perinitting it to flow-through the framework in one entire mass, and direct each stratum obliquely downward. In rear of the baffle plates, in turn,- Idispose .a plurality of series of-my improved eliminating plates, there be ing as many series as necessar'y'to thoroughly wash and cleanse the air and. the series being duplicates of each other, and there being as many members or plates in each series as the of my present inventionisiconstructed as follows Itsforward for eliminating leaf 10 is perhaps -2 t0 6 incheswide. and is inclined upward toward the rear at anlangle o-fthirty into agutter 12 standing at the rear edge of the leaf 'l; 0 .(this gutter being shown angular in Figa iand semi-circular at 12. in Fig. .6)

and the: rear Wall- 1?) of saidi'gutter rises higher than its: front wall andto a point practically in linewithfthe plane of the leaf :10- extended', as the dotted line in Fig. 4: will Show; and at its upper edge above the gut.-

ter 12 thi'swall is continued into a shield 14 degrees 'to the horizontal, here the plate is bent, at an acute anglelli and then ,formed' which is'deflected forward over thegutter to the eliininatingleaf of the plate nextare inclined slightly toward their several j in tl'llS condition it strikes the underside of i gutter 12, while the air itself passes off the made of one rather wide strip of' meta lzjfljhe that the folds or partsfo'rmingthe walls of {:the gutters are projected at one end'j f the and stands at an acute angle to the plane of said leaf 10. The other or deflecting leaf l5 extends from the lower portion of the rear wall 12-3 of the gutter obliquely downward, and serves the same function with respect in the rear that the battle plate 5 above re ferred to serves with respect to the eliminating leaf 10 of the plate I am now describing In Fig. t the deflecting leaf 15 is riveted at 16 tefthe rear wall 13,;whereas in Fig. ,6 the"- wall 13 and shield 14 are foldedbaclQupon each other as at 17 andbent integrally a'siat 18 into the leaf 1?) so that the entire platefisfl last-named view also shows the fronttand rear edges of both leaves as reversely bent back as shown at 1'9, but this'detail isl nojj important. j

Each series' of plates above w comprises several of those just-dose bed; superimposed above and spaced from"each; otheras seen in Fig; l-,-ftind so constructed;

plate in order that they may enter an up-', right pipe 20 along this side of the framework, and all the plates in'the several series pipes 20. The latter deliver at their lowery ends ontoa commo floor-21 which also ifs inclined toward a d delivers into a sump 22 wherein the water may be-boiledonfil-v tered or from which it can be delivered into i the sewer or other waste, but if it is purified in any manner itcan be taken from this;

sump and jetted again into the apparatus 7 as described above. a With this construction of parts, the blast,

of air enters the front of the apparatus as" indicated by the arrows, passes first to and through the spray caused by the various jets I and is thereby thoroughly moistened, and

the downwardly inclined baflies 5 and is cut upinto horizontal strata and directed obliquely downward onto the eliminating leaves'lO vof the plates in the first series; here its forward impulse carries the thoroughly saturatedair (mist) up the gently inclined, leaf 10 so that the water moves with the air, and when the acute angle 11 is reached the moisture passes over into the gutter 12 while the air continues upward along the course. indicated by the dotted line in Fig. 4 and strikes the forward face of the shield 14; here any surplus moisture is taken out of the air and falls'back into the face of the shield andover its upper edge, and thence onward to the underside of the deflecting leaf 15of thisseries immediately" above; by this leaf it is deflected again downward and permitted to pass on, to the corresponding plate in the series next to the rear.

The water thus extracted from the air drops into the gutter which, being inclined slightly to one side, causes it to flow toward and dc livers it into the pipe 20, and all the various pipes 20 deliver onto the floor 21, and the' latter into the sump. Thus it will be seen', that at no point throughout the course of this apparatus is the water flowing over the plates or battles in a direction the reverse of that followed by the air, and at no point is-the water dripping across the air which. flatter may be-passing through the apparatus 'a tiaconsiderable velocity depending on the rapidity with which the fan or blower is re- =vo11ed. 11ave sought in this apparatus to break upwthe water solely by the jet nozzles 'j'andnot bythe force of the air, and it is my irtention toiise the latter to throw the spray i s r 'iorljperr nit it to move thereon in a natural mannerjrather than in a manner contrary to thahi'ndu'cled by the current of air and there:

0 'water particles on the several di'fierent surf'ces; or leaves of the plates and to cause "fore /lia' -ble to cause t-ro'uble; By this state"- qiienthlfrnean that I, havefound that water flowin'gTin a direction the reverse of that foll'dvfed by the air, or dripping or splash ing iacrbss the air,-is likel-y to'be'taken up againz'and carried forward so that the air issuing from the rear end of the apparatus function of taking-the moisture out of the air so that the latter issues from the rear end of the apparatus pure and cool and moistened to a degree only dependent upon unduly moistened; but I have found that with this apparatus the jet nozzles perform the function of moistening and washing the air near the front end of the apparatus, and I 'the various series of plates perform the 0 rection in which the air is flowing, a gutter across the upper edge of said plate and dropped below its projected plane, and'a shield rising from in rear of said gutter to a point above said plane.
